Mortimer was born in Virginia and grew up in Richmond, VA. Her father is George Riley Mercer Jr., a wealthy real-estate investor, and her mother is Dale Mercer (née Tatum), an interior designer. Her paternal grandfather, George Riley Mercer Sr., founded Mercer Rug Cleansing in 1936. Mortimer is reportedly a descendant of Thomas Jefferson (on her mother's side) and relatives of Patrick Henry and James Madison (on her father's side). She grew up with one sister, Dabney Mercer. Mortimer attended the Lawrenceville School, where she was a member of the Kirby House. She went to University of North Carolina at Chapel Hill, before transferring to Columbia University, where she was a member of St. Anthony Hall. She graduated from Columbia with a BA in art history.
Mortimer has a line of handbags and clothing in Japan for Samantha Thavasa, for which she was featured in an advertising campaign. She also features prominently in Samantha Thavasa USA's online promotional materials and in the company's Madison Avenue store, which also carries her handbags. She subsequently formed her own clothing line, Riccime by Tinsley Mortimer, which is available in select stores in Japan, including Isetan. In 2008 Mortimer became involved in branding and design for a condominium development.
She made a cameo appearance on the season two premiere episode of Gossip Girl, which aired September 1, 2008 on The CW. On March 10, 2010 her own reality television show created by Andrew Glassman and Mike Aho for The CW called High Society, where she stars along with other socialites such as Paul Johnson Calderon and Devorah Rose, first aired. It documents the lives of her and her friends but cancelled after eight episodes.
Mortimer wrote a book titled "Southern Charm", which follows Minty Davenport from South Carolina to New York where she is the victim of rumors. It was published by Simon & Schuster in April 2013. Mortimer also contributed a section to the best selling book entitled The Park Avenue Diet  which outlined recommendations on how to perfect your conversation and social skills. The book was written by Manhattan diet doctor Stuart Fischer.
Mortimer met Robert Livingston "Topper" Mortimer at Lawrenceville School and eloped when they were both 18. However, their parents forced them to annul the marriage. On May 4, 2002, they remarried in Richmond, Virginia. The Mortimers are now divorced.
